This invention relates to a machine more particularly designed for operating `on textile `threads where it isv desired that these threads be not stopped during their operation because of possible injury to the same and is particularly illustrated in this application as applied to a Warp-sizing machine, which I willdescribe in detail altho uses on other similar machines will be understood as being contemplated by this invention.

One of the objects of the invention is to pro-kv vide a means by which the warps during sizingwill be constantly driven so as to prevent injury of the same from the heating oi the drying drums.

Another object of the invention is the pro-` vision of driving means to drive the Awarps ata relatively'slow rate of speed'while the ends are being pieced, without detrimentally aflecting the relatively high speed operation of the warps during the period when no piecing up of the ends or other work is necessary. r

Another object of the invention is the provision of a relatively fast and relatively slow rate of speed 'both positivelyand continuously,-con nected to a drive for the machinewith an arrangement so that when the relatively high speed drive is used the relatively' slow speed drive will run lfree and will pick `up being driven at' this higher rate of speed. A further objectof'` l vision of relatively slow speed'electric driving motor to be used in connection with a relatively high speed driving motor with a positive connection of the slow motor to the drive for themachine thru an overrunning clutch so that so long as the high speedV motor is in operation the slow motor 'willbe ineffectual but as soon as the high speed motor discontinued then the drive will be carried on by the 'slow speed motor driving thru the overrunning clutch.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. In the accompanying drawings:` Y Fig. 1 is a side elevation in a more or less diagrammatic arrangement of a warp-sizing machine, illustrating particularly the drives and the connection of my slow speed motor to the main driving gear.

Fig. 6'is -a diagrammatic view illustrating the relative position of the machine and the several stations from which' my control may be operated. In practice, it has been found that'in sizing the overrunn'ing warps-which-are of rayon, celaneses or other syn-l thetic formation, in running them upon the usual cotton warping machines they frequently become detrimentally affected by` a stopping of the machine for piecing the ends and allowing these synthetic fibers to Contact with the drying drums-without moving thereacross,- altho Yin cotton warps when-usedon the machine no such detrimentalv action occurs. In the operation of such amachine; however, the operators cannot piece up the threads during the usual relatively ,d

high rate of travel ofthe warps thru 'the machine and in order to piece up the threadsit was necessary to stop the machine or to slow it down thru a Reeves drive or the like, requiring a rather lengthy operation and requiring a further similar length operation to speed up the machine to the required travel, and in order to speed up the operation of iilling the beam and also provide a positive means vwhereby the warp will notstop in its travel over the heating drying drums, I have provided a slow speed motor and connectedY itpositively to the drive mechanism of the machine thru an overrunning clutch so that the relatively iast drive of the machine may be shut oi and this slow speed motor will pick up and drive the warps overthe heated drying drums, whereby the same will not become injured as would occur by stopping the machine and yet the movement is so slow that the operator may piecevup the ends'during the travel of the yarn from the machine and Iy havel provided undue strain on the yarn and materially `speeds up production and the arrangement which I have provided is so simplethat it is comparatively inexpensivev to install for its complete and positive actuation of' the machine; and the `iollowing is a more detailed description of the pres ent embodiment of this invention illustrating the preferred means by which these vadvantageous results may be accomplished:-

' erally 83 andumore fully illustrated in Figs. l-

With reference to the drawings, I have indicated in Fig. 1, a more or less diagrammatic view of the framework consisting of uprights 10 and horizontals l1, 12 and 13 upon which the bearings for the different rotating parts of the machine are 'mounted The warp threads 14 are drawn from a plurality of section beams 15, 16, 17 etc., thru a reed 18 which may be adjustable over the bars 19 and 20, between which there may be a lease 21, thence thru the slashing rolls 22 and 23, where a sizing 24 in a trough 25 is applied by means of a roll 26, thence over a series of drying drums 27, 28, 29, 30 and 31, each of which is provided with steam suiilcientto heat it to the desired degree, around substantially 200 Fahrenheit.

Steam pipes to each of the drums are illustrated generallyat 32 and the usual siphony arrangement for picking up the steam condensation and extracting it from the drums is provided which is not shown in this disclosure.

'I'he warps travel over a guide rolle'r 33 and are then reeled on a warp beam 34, which has adjustable heads to accommodate thel varying. widths in which the beam is to be formed.

The main driven element or gear 35 is mounted on the main drive shaft 36 of the machine upon which there is a clutch 3 7 for controlling the operation of the machine. This clutch is operated by a shift lever 38 extending out to a handle 39 for convenient manipulation. Upon this driven shaft 36, there is a pulley 40 which drives pulley 41 by means of a belt 42 which affords a slip friction connection in the conventional way as shown in Patent No. 1,540,- 265 dated June 2, 1925 and which in turn drives gear 43 and gear 44 connected to the packaging warp beam 34.

I'here is-also mounted upon the main'. drive shaft 36 a gear 45 which drives gearv46 on the same shaft with gear 47, which latter in turn engages the teeth 48 on the heated drum 31 from which the remaining drums are driven thru suitable pinions 49 and 50 transmitting motion throughout the train. The slashing rolls are driven vfrom the gear 60- by gear 61, pulley 62, belt 63, gears 64 and 65, all of which drive is more or less conventional in a machine of this character.

A relatively high speed motor 70 is mounted upon a bracket 71 on the frame of the machine and drives gear 72 which meshes with ythe main Ydrive gear 35 4thru a Reeves drive consisting of Y pulleys 73, 74with a V\ belt 75 between them, pulley 74 being driven by gear 76 on shaft 77 and belt `78connected with gear 79 on the motor 70. 'I'he effective speed, of course, of this motor may be varied by reason of the adjustment o1' the Reeves drive toY separate the pulleys 73 and 74, as desired. l v l A relatively slow speed motor 80 is provided with suitable helical reducing gears to drive shaft 81 upon which there is mounted a gear 82 directly engaging the main driven element or gear 35. This gear 82 is connected to the shaft 81 thru an oyerrunning clutch designated gen- The shaft 81 is reduced as at 84 at its end,

providing a shoulder 85. The overrunning clutch designated generally 83 consists of a casing 86 in which there is provided a hardened bushing 87, which directly engages and rotates on the smaller portion 84 of the -shaft and is spaced from the shoulder 85 by a washer 91. Upon this `the larger part 81 of theV shaft. The part 93 of this ball bearing snugly ts the shaft 81 while the part 94 snugly engages the sleeve 90 with the balls 95 rotatably located between these parts. 'I'hus the casing is so mounted that it may be rotated relatively to the shaft, if such force is applied to it to cause it to have this movement.

The casing 86 also has a unit tightly fitting therein, consisting of a cylindrical shell 96 having two inwardly extending fins 97 between which there are mounted rollers 98, prevented from axial movement by these fins, while there is a drum 99 keyed as at 100 to the shaft 84 which has a plurality of notches 101 in it in each Y of which one of the rollers 98 is located. Each of these notches has a surface 102 which extends towards the shell 96 so that should the roller move along this surface towards the shell it would be wedged and bound by its engagement therewith, while when it is against the abutment 103 of the notch it may rotate freely in the notch, whereby free relative rotation of these parts ispermitted. A cap 104 is screwed into the end of the casing to house these parts therein.

The arrangement is thus such that if the shaft 81 rotates in the direction of the arrow A, or clockwise as in Fig. 5, the rollers will move t0 binding position and will drive the casing 86 the gear thereon and any parts to which it is connected; while if the casing were driven in the direction of arrow A faster than the shaft 81, there would be a free rotation of the parts by reason of the rolling of the rollers 98.

The machine as a whole designated 105 in Fig. 6 has any desired number of stations 106, 107

located at convenient points about the machine for the control thereof. At each station there is a two button switch. Pressure on one button 108 will cause the high speed motor 70 to stop by reason of disconnecting the power from the Operation In the operation of this machine, I cause the constant drive of the motor 80 at a speed which will cause the warps to move thru the machine at a slow rate of speed, which will be sumcient to prevent injury by the heat from the drying drums and the motion will be sufllciently slow so that the operator can piece up the ends in the space between the section beams 15, 16 and 17 and the reed or at other points of the machine as they pass therethrough. When the warps are intact the relatively high speed motor is thrown into operation at one of the stations 106 or 107 and will pick up the load and cause the warps to travel therethrough at a high rate of-speed. This high speed drive will be 'free from the low speed motor by reason of the overrunning clutch described permitting this action without rotation of the helical gears of the slow speed motor which at the high rate speed would be detrimental to their life.

Should an operator observe a break in any of the ends, he will shut olf the high speed motor permitting the slow speed motor to cause the warps to travel slowly thru theY machine and allow suflicient time for any broken down ends to be pieced up after which the high speedmotor will again be caused to pick up the load and move the warps at a high rate of speed, which makes unnecessary the slowing down of the machine thru the Reeves drive which is a lengthy operation and also eliminates the necessity of the operator shutting off the machine by the clutch 37 which will injure synthetic yarns. This control of the motor 'I0 may be from any point about the machine, which I have illustrated at 106 and 107, thus permitting nicer control of the machine than has heretofore been possible.

It will be remembered that machines of this character are some 25 to 30 feet long and the operator has to walk about the same to any chine, the field of the motor '70 is dead allowing the armature to turn freely while, of course, the overrunning clutch permits the operation at the faster rateof speed without similarly driving the motor 80.
